Références dans la base de données de sécurité :

Dans le dictionnaire CVE du Mitre : CVE-2000-1174.

Plus de précisions :

La bibliothèque graphique ncurses embarquée dans Debian GNU/Linux 2.2 est vulnérable à de nombreux débordements de capacité lors de l'analyse des fichiers de données de terminfo. Ce problème a été découvert par Jouko Pynnönen <jouko@solutions.fi>. Ces problèmes sont seulement exploitables en présence de binaires setuid liés à ncurses qui utilisent ces fonctions particulières, ce qui inclut les versions antérieures à xmcd 2.5pl1-7.1.

Ce problème a été résolu dans le paquet ncurses 5.0-6.0potato1 pour la Debian GNU/Linux 2.2 et ncurses 5.0-8 dans sa version instable.

Corrigé dans :

Debian GNU/Linux 2.2 (potato)
